Concentrating on what might be bigger differences at first
22>23
There were some definite downgrades for me
Norway was popular in 23 but way more distinctive in 22 for me. 21 was more memorable as well.
Greece has been quite good recently but this year didn't work in any way. They went the Western pop route still but this time with a wholly Greek singer.
Iceland the last couple of years good, but this year the song really wasn't worth much even if the vocal was decent.
Netherlands came good last year, but not this year bringing something that looked backwards.
Azerbaijan wasn't bad this year but I feel 22 will be remembered much more
Cyprus wasn't bad this year, but felt much fresher in 22
[Montenegro was missed after Vladana]
Finland better song though 23 fun
CZ both good but I think 22 will last more
Spain more immediate though not a favourite, the 23 one is growing on me
Armenia was good but perhaps 23 was more memorable
Ireland better in 21 but neither that good
San Marino got worse, but neither that good
Israel more popular in 23 but probably slightly worse
Estonia was more fun in 22, thought I respect 23
Ukraine better but not a favourite of mine
Sweden better but I didn't love it
Serbia better, though both decent
Albania more distinctive but still patchy for me
Swiss this year I guess, but don't like either
Denmark this year but not a fan really
UK - Ryder can sing though song overrated
France - I suppose it's ok
Italy, overrated, but more interesting than 23
Croatia obviously
Lithuania classy song holds together better
23>22
upgrades
Latvia was a pretty big improvement I feel, couldn't stand the 22 song.
Germany was better no doubt
Malta was better
Poland - I always felt River was overrated (though great part near the end before final chorus), but 23 was fun I guess
Austria more interesting song
I don't think Georgia was bad in 22 but it was spectacular in 23
Australia better but neither song likely that good
Slovenia better maybe, the performance helps
Romania better but not a favourite still
Belgium better but still not something that will last
Moldova better but not really caring about either
Portugal had more character to it at least
2022 - 25
2023 - 12
Even if you disagree with songs like PL or CZ it still looks a landslide. I might change minds on Spain, hard to say, such different styles.
2021 - 21
2022 - 15
So it's a downward direction since the pandemic, 2021 I suppose had more for the returning acts to get a good song together.
